the mom is a former psychologist turned life coach/spiritual "guru" of sorts and their dad is a botanist who grows commercial marijuana and is a decriminalization activist. they're together but have been in an open relationship for 40+ years and even have kids with other people, they're not married or anything and live separately since the mom is always traveling/touring for work and dad has to maintain the farm that's just outside SF. it's all very hippie poly nonsense.
